ABSTRACT:
A microprocessor comprises an execution controller for storing a transfer source address and a transfer destination address and for generating a transfer start signal, and a data controller responding to the transfer start signal so as to continuously and repeatedly perform a storing of a transfer data and a transfer of the stored data to a transfer destination, while inhibiting execution of the execution controller during a period of execution of the data transfer. In addition, a counter circuit is provided to count the number of items of data which have been transferred by the data controller. When the data transfer has been completed, the inhibition of the execution of the execution controller is cancelled, and the transfer source address and the transfer destination address in the execution controller is modified in accordance with the number of items of data counted by the counter circuit.
